Describes something as neither especially good nor especially bad: average, ordinary, or at the usual level. Often used as 並みの or 並みだ.

Ordinary effort will not be enough to pass this exam.

noun, noun which may take the genitive case particle 'no'
regular grade; mid-grade item
Used for the standard or regular grade of an item, especially in menus or product rankings, often contrasted with 上 or 特上. The spelling 並 is especially common in this use.
うな重の並を二つください。
Two regular-grade eel boxes, please.
noun, used as a suffix
on par with; equivalent to; at the same level as
Suffix use after a noun, meaning that something reaches the same level as that noun: プロ並み, 人並み, 大人並み, etc.
彼女の料理の腕前はプロ並みだ。
Her cooking skill is on par with a professional's.
この子は大人並みに難しい本を読む。
This child reads difficult books at an adult level.
noun, used as a suffix
Limited suffix use meaning 'each' or 'every,' as in older or fixed expressions such as 月並み in the sense 'monthly; every month.' In modern Japanese, 月並み is more often understood as 'commonplace,' so this use is context-dependent.
「月並み」は、古くは「毎月の」という意味でも使われた。
月並み was also used in the older sense of 'monthly' or 'every month.'
noun, used as a suffix
row of; line of
Suffix use for things arranged in a row or line, especially in common compounds such as 歯並み, 家並み, and 町並み.
矯正して歯並みがよくなった。
My teeth became better aligned after orthodontic treatment.
川沿いに古い家並みが続いている。
A row of old houses continues along the river.
普通 broadly means normal or usual; 並み emphasizes an average level or grade, often with comparison to better or worse levels.
平均 is a numerical or statistical average, while 並み can be a looser judgment of ordinary quality, ability, or grade.
標準 means a standard or norm to use as a reference; 並み describes something as at an ordinary or regular level.
The spelling 並 is associated with things lined up side by side and, by extension, being at the same level. This supports the senses of average level, equal level as a suffix, and rows or lines in compounds.
